Struct HookState 

pub struct HookState {
    pub func: Option<Value>,
    pub rust_func: Option<RustDebugHook>,
    pub call: bool,
    pub ret: bool,
    pub line: bool,
    pub count: bool,
    pub count_base: i64,
    pub count_left: i64,
}

Per-thread debug hook state (PUC lua_State hook/hookmask/basehookcount/ hookcount). func is the Lua hook; the booleans are the PUC mask bits.

Fields

func: Option<Value>

the hook function (None when no hook is installed)

rust_func: Option<RustDebugHook>

v1.1 B11 — Rust-side debug hook. Fires alongside the Lua hook (Rust first); both can be installed simultaneously, but most embedders pick one.

call: bool

LUA_MASKCALL — fire on function entry

ret: bool

LUA_MASKRET — fire on function return

line: bool

LUA_MASKLINE — fire on source-line change

count: bool

LUA_MASKCOUNT — fire every count_base instructions

count_base: i64

instruction count between count events (PUC basehookcount)

count_left: i64

instructions left until the next count event (PUC hookcount)

fn clone_from(&mut self, source: &Self)

Performs copy-assignment from source.

impl Copy for HookState

impl Default for HookState

fn default() -> HookState

Returns the “default value” for a type.
